Without doubt, in medicine as in life, one size does not fit all. We do not administer the same drug or dose to every patient at all times, so why then would we live under the illusion that we should give the same nutrition at all times in the continuum of critical illness?

What if this is incorrect?

Recent data indicate that early underfeeding of calories trophic feeding may have benefits and may require consideration in well-nourished patients. To begin to answer this question, we must look to the landmark Minnesota Starvation Study from Recent and historic data indicate that critical illness is characterized by early massive catabolism, LBM loss, and escalating hypermetabolism that can persist for months or years. Post resuscitation, increasing protein 1. Malnutrition screening is essential and parenteral nutrition can be safely added following resuscitation when enteral nutrition is failing based on pre-illness malnutrition and LBM status.

We do not administer the same drug or dose of drug to every patient at all times, so why would we live under the illusion that we should give the same nutrition or amount of nutrition at all times? What if this is, and has always been, incorrect? Further, recent data have indicated that early hypocaloric feeding so-called trophic feeding may be superior [ 12 ]. Could there be some truth to this? The war had left hundreds of thousands starving in Europe and Asia, and rebuilding these nations would not be possible with much of the world suffering from a lack of basic nutrition.

US soldiers entering liberated European cities found emaciated, cachectic, and starved civilians surviving on meager portions of potatoes, bread, and little more. At that time, very little knowledge existed about the fundamental nutritional needs in humans.

Thus, the USA and other nations wishing to support relief efforts worldwide realized a greater understanding of how to deal with refeeding and the nutrition delivery required to recover from severe starvation was desperately needed.

How else would nations supplying the life-saving food relief know how much was needed to ensure recovery? For further details, see the excellent summary by Kalm and Semba [ 6 ]. However, due to religious beliefs, morals, or conscience some chose not to fight. These individuals became known as conscientious objectors COs —COs were commonly sent to do menial jobs like building ro, forestry work, and other peaceful homeland contributions. However, in Keys gave a few heroic COs a chance to contribute in a legendary way.

Keys obtained approval from the War Department to find healthy men from the 12, COs registered across the country. After extensive screening and explanation of the trial, 36 subjects were selected for the study. As with most great scientific and medical endeavors, this experiment was tly funded by the government Office of the Surgeon Generalfoundational support from religious groups including Mennonites, Brethren, Quakers, and Unitariansand private industry funding. Thus, on November 19,36 healthy young men entered the brick confines of the Laboratory of Physiological Hygiene, located in the South Tower of the football stadium at the University of Minnesota.

Minnesota Starvation Study recruitment brochure from May 27, Adapted from [ 6 ]. Extensive physiologic, cognitive, intelligence, and laboratory testing was conducted throughout the experiment. The starvation diet was created to consist of foods reflecting the diet experienced in the war-torn areas of Europe i. The effects of the semi-starvation diet were quick and striking. Men in the study lost weight rapidly and all men developed ificant edema from protein malnutrition. Subjects rapidly demonstrated a remarkable decline in strength and energy.

All subjects complained that they felt old and constantly fatigued. ificant depression, anxiety, neurologic deficits, and loss of interest in sex occurred. Men become obsessed with food and cheating on the diet became an issue. He began having vivid, disturbing dreams of cannibalism in which he would consume the flesh of an old man. On trips into town, before the buddy system had been implemented, he was known to cheat extravagantly on the starvation diet, downing milkshakes and ice cream.

Finally, Keys confronted him, and Watkins broke down crying. Watkins then became agitated and threatened to kill Keys and take his own life. Keys immediately dismissed Watkins from the study and had him admitted to the psychiatric ward of the university hospital.

This study received a great deal of national attention, including a prominent depiction in Life magazine in July Fig. Photograph from Life magazine on July 30, volume 19, 5, p. By the end of the 6-month starvation period, the men had lost almost a quarter of their weight, dropping from an average of The average heart rates of the subjects slowed dramatically, from an average of 55 to 35 beats per minute. The last day of the starvation period July 28, was met with great enthusiasm and anticipation by the men.

However, July 29,did not prove to be the reprieve they had anticipated. Very little appreciable weight gain occurred in any of the groups and some men continued to lose weight on the increased calorie diets. This finally led to successful weight gain in the starving men.

To attempt to assist post-war relief efforts, Keys released early related to the most effective of the various rehabilitation diets before the experiment even ended [ 78 ]. At a scientific meeting in Chicago, Keys noted:. Enough food must be supplied to allow tissues destroyed during starvation to be rebuilt … our experiments have shown that in an adult man no appreciable rehabilitation can take place on a diet of calories [actually kcal] a day.

The proper level is more like [ kcal] daily for some months. The study officially ended on November 20, Some of the men were noted to take in as much as 11, calories in a single day! For many months, the men reported having a sensation of hunger they could not satisfy, no matter how much they ate. In these fully healthy, young men, recovery to a normal weight took an average of between 6 months and 2 years. No appreciable long-term or permanent adverse effects were noted in the subjects. This work led to the landmark two-volume, publication The Biology of Human Starvation in [ 5 ]. This seems excessive as we think of the obesity epidemic and excess of caloric intake often present in the First World clearly not true in many developing countries ; however, based on the World Health Organization WHO and the Food and Agriculture Organization of the United Nations, this is not far from current WHO recommendations.

Current data presented in Table 1 indicate that for a moderately active kg individual 1. Interestingly, this calorie delivery is virtually identical to the control period of the Minnesota Study. Summary of caloric needs of critically ill and healthy individuals in the context of the Minnesota Starvation Study and actual current ICU calorie delivery. As we begin to examine how to deliver targeted calorie and protein delivery based on actual physiologically measured targets in critical illness, we must examine the existing data for caloric need in the different phases of critical illness.

This evolutionarily conserved response allows the stressed or injured human to generate energy to escape its attacker and recover from initial injuries. This is described in much greater detail by Oshima et al. Further, we know that the early acute phase of sepsis and trauma are not hypermetabolic states, but rather the patients have a TEE to resting energy expenditure REE ratio of 1. Thus, caloric need does not increase in the early phases of injury first few days post injury.

As presented in Table 1data from Uehara et al. In younger trauma patients mean age 34Uehara et al. With the onset of early ICU mobility programs, this may increase further as activity increases. Thus, as presented in Table 2sources of energy supply transition in critical illness from largely endogenous supplies and release of energy early in illness to the need for primarily exogenous energy delivery in the late or recovery phase [ 11 ]. These data suggest we should consider feeding less nonprotein calories early in the acute phase first 24—96 hours of critical illness and markedly increase calorie delivery during recovery as illustrated in Fig.

A recent randomized, double-blind, controlled trial administered mg thiamine to patients with septic shock and elevated lactate [ 14 ]. Administration of thiamine did not improve lactate levels or other outcomes in the overall group of patients with septic shock and elevated lactate. Substrate mobilization in catabolic response to stress and injury during acute phase. Adapted from [ 9 ]. Adapted from [ 11 ]. Proposal for targeted nutrition delivery across phases of critical illness. Adapted from [ 18 ]. At the same time, it is also well known that protein losses increase 4-fold in the first 24 hours of critical illness [ 15 ] and we are exceedingly poor at meeting these needs [ 15 ].

Unfortunately, large, international surveys indicate that we as ICU practitioners deliver an average of 0.

This is one-third to one-half of the latest ICU guideline-recommended protein delivery of 1. Reduced calorie delivery during the acute phase is likely not applicable in malnourished patents i. These data reveal that the average for calories delivered in the ICU over the first 12 days is kcal and 47 g of protein Table 1 [ 16 ]. This period is far longer than the first 1—5 days of the acute phase where hypocaloric feeding with adequate protein may make physiologic sense. These data confirm that ICU patients worldwide average far less energy and protein than in the legendary Minnesota Starvation Study, a study that would likely never be repeated today due to questions around the ethics of inducing potentially life-threatening starvation in a healthy volunteer.

Yet it appears to be quite acceptable to actively starve ICU patients worldwide, and to a much more severe degree then the men in Minnesota suffered which drove many of the men nearly to the point of insanity.
